Prevent Duplicate Record Insertion on browser Refresh mysql | php
MySQL insert and prevent duplicate records on browser refresh | PHP, implement server-side validation by checking if the submitted data already exists in the database before inserting. Utilize PHP to query the database and verify the data's existence, then execute the insertion only if it's not a duplicate. Employ techniques like checking unique constraints, using SELECT queries, and session-based flags to ensure new records are added while preventing duplicates upon browser refresh.

I am new to PHP MYSQL . I was writing a code on how to insert data . Record has been added. Again when I refresh, that old record gets automatically added to the database. That time I have visited your website and saw this demo. I have made the changes , it really worked like a magic with 100% results without any error. Whoever you are , Thank you very much.

[@madhumadhu-tk2eq]

Record save two times, how to solve that issues?

[@stevenneuberger4323]

This would be a better demonstration if mysqli with prepare statements were used. PHP mysql is deprecated and implementing an INSERT in this manner wouldn't handle single quotes in the input, e.g, a last name of O'Connor would cause a nasty error.

I realize Im pretty off topic but does anyone know of a good place to watch new tv shows online?

[@mohammadabrar7854]

Still you can insert duplicate data, you have to write code in php to whether data already exists or not in the database or else it will insert

[@mahirzebari3646]

thanks bro that is my problem😍

[@marineoutsource]

But when you press the back button the same data will be retained and when you click submit, you still have the same records . . . any solution to prevent it?

[@kevinpeters1780]

Does anyone actually know what causes two records to be inserted ? Is it a response and reply time lag issue?

[@dhanushmahesh1682]

it is POST REDIRECT GET problem

[@srinivasaraoyp3640]

if (mysqli_query($conn, $sql)) {
header("Location:contact.php");
// echo "New record has been added successfully !";
} else {
echo "Error: " . $sql . ":-" . mysqli_error($conn);
}
mysqli_close($conn);

[@akashkhandelwal1869]

This is not the solution to stop duplicate values. if the user himself inserting the same values than it will be inserting into database. Try to improve your answer .
